Title: Alarm clock
Inventor: YAMAGUCHI YOSHITO
IPC: G04C23/02
Filed: 1988-09-07
Abstract: PURPOSE:To set and verify time of alarming without increasing second pointer count by using a second pointer as a reference pointer. CONSTITUTION:Contents of a second counter 28 are preset in a minute memory 58 and an hour memory 62 by a preset circuit 38, and alarming time is set based on the indication of a second pointer. When an alarm-on signal is output from an alarm switch circuit 86, the second pointer is rapidly fed by a signal from a 1st rapid traverse circuit 96 and the movement of the second pointer is detected by a second pointer counter 74. A 2nd coincidence detection circuit 76 stops the rapid traverse of the second pointer after the second pointer has been rapidly fed to the position of alarming time. With the alarm-on signal generated, a stepping stop circuit 100 outputs a stop signal, and since a signal switch circuit 18 stops a reference frequency signal from a reference signal source 10 to a motor, the second pointer is stopped. At this time, with a 3rd rapid traverse circuit 118 memorizing that a coincidence signal is output from the circuit 76, every time the coincidence signal is output from the circuit 118, the second pointer is rotated one turn by rapid traverse once per minute.

Abstract: PURPOSE:To ensure initializing with a reset signal independently of the operating state of an oscillation circuit by using the reset signal to attain initialization through a noise elimination circuit when an oscillation circuit is in operation and using the reset signal to attain initialization directly when the oscillation circuit is at a halt. CONSTITUTION:An oscillation stop detection circuit 6 detects the stop of an oscillation circuit 1 depending on the state of a 1st frequency division signal 4 and outputs a detection signal 11 when the oscillation is stopped. A noise elimination circuit 8 compares a pulse width of a reset signal 9 with that of a 2nd frequency division signal 5 and when the pulse width of the signal 9 is more than a setting value, the circuit 8 outputs a 1st initializing signal 12. A bypass circuit 13 adds the signal 9 to the signal 12 not through the noise elimination circuit 8 when the detection signal 11 is inputted to the circuit 13 to output an initializing signal 10. When the oscillation circuit 1 is in normal operation, the signal 11 goes to a low level and the noise elimination circuit 8 eliminates noise from the signal 9 and when the pulse width of the signal 9 is more than the setting value, the semiconductor device is initialized. When the circuit 1 is stopped, the signal 11 goes to a high level and the signal 9 is used to initialize the semiconductor device not through the circuit 8.

Title: Image a/d conversion circuit
Inventor: MARUNO YOSHIMARU
IPC: H04N1/40
Filed: 1984-10-25
Abstract: PURPOSE:To unify a gradation distribution and to eliminate DC drift that causes unstability of a CCD output by converting an input video signal and comparing digital output and each black/white reference levels, and controlling a range of the A/D conversion. CONSTITUTION:The input video signal is converted to a digital signal and compared to each of the blach/white reference levels, in a manner that the conversion output is compared to an output of a reference value generator 7 equivalent to 0IRE at each 1 sample value 8. A comparison output is converted to DC mode by an integration circuit 9 and added as a DC component to the input video signal via an adder 2. The conversion output above is compared to an output of reference value generator 5 equivalent to 100IRE at each 1 sample value, of which comparison output will be applied to a reference input terminal ref of an A/D converter 3 via an integration circuit 6. In this manner, an A/D conversion ratio is made variable. By means of such a feedback control of A/D output as above, the A/D conversion is performed within a range from 0IRE to 100IRE for each peak, regardless of peak levels of black and white of the input video signal. By this an uniformity of image gradation is obtained.

Filed: 1990-08-27
Abstract: PURPOSE:To test wafers automatically without removing a probe card and enhance the rate of operation by installing an insulation board having a certain level of insulation resistance which allow electric current to flow, the current being smaller than a current value of a minimum resolution by a tester. CONSTITUTION:An insulation board is set up on a stage where the insulation board has a certain level of insulation resistance which allows electric current to flow, the current being smaller than a current value of a minimum resolution by a tester. The elevation of a stage surface and the thickness of a wafer placed on the stage are measured with a capacitance sensor. The measurement results and the wafer's height placed in contact with a probe for a probe card are stored and the insulation board set up on the stage is carried under the probe based on the measurement results of the wafer where a measurement condition setting change signal is output to the tester. The height of the insulation board which is brought in contact with the probe is determined based on the height data stored. Then, the stage is made to rise up to a position where an arbitrary setting value is added to the height so as to inspect the characteristics of the probe card with the tester. This construction makes it possible to inspect automatically wafers without removing the probe card and hence improve the rate of operation.
